I always dislike washing pots, especially when rice is stuck to it. Solution: bake in disposable pan and throw (recycle) when finished.

Easy recipe:
pour a bit of oil and lotsa chopped onions in to pan. Bake, uncovered at 400 for 30 minutes. When it smells and looks right, add rice and water (check your package), and any other spices.
Cover pan and bake at 350 for 30-40 minutes.

Easy to make, easy to clean (thats my trick)
